ber 25, 1931 6 Claims.

This invention relates to a means for preparing a liquid by the use of acombination member which consists of a cartridge in which is contained adrink ingredient and carbon dioxide gas, the cartridge being made in twoparts, an inner gas cartridge and a drink ingredient shell which holdsthe gas cartridge, the shell being arranged to be forced 01T the gascartridge to release the ingredient which is blown out by release of thegas, all as set forth in application Serial No. 602,378, the divisionalmatter in this application relating particularly to a bottle-likereceptacle in which the rell unit is held and operated upon bymanipulation of parts of said bottle.

The particular object of the invention is to provide a bottle in which acarbonated beverage can be made by the use of a refill member containinga drink ingredient and a gas, which provides means for the propersupport of the refill, permits movement of the parts of the bottle toseparate the parts of the refill to permit charging of the liquidcontents of the bottle and subsequent'release of the top pressure causedby the release of the gas, so that the bottle can be opened without thecontents boiling over the top thereof.V

The invention also reduces the cost incident to the use of glass bottlesin which beverages are usually sold in that it entirely eliminates theglass bottle, the necessity of sterilizing the same, and the cost ofshipment to and from a bottling plant.`

' With these and other objects in view, the invention comprises theconstruction, combination and arrangement of parts as hereinafterdescribed and then particularly pointed out in the appended claims.

This application is a division of application Serial No. 602,378, nowPatent No. 2,073,273, dated March 9, 1937, which in turn is a continuingapplication of Serial No. 498,095 filed November 25, 1930.

Referring to the drawings in detail, 5 indicates a liquid receptacle ofbottle shape of any contour desired and preferably made fromnon-corrosive metal. The bottle is provided with an inwardly extendingflange 6 adjacent its open end for the support of the bridge disk 1,whose center strap 8 is concave and acts as a self-centering andsupporting agent for the rell member, to be later referred to.

The receptacle or bottle 5 is provided with a shoulder 9 and extendedlips I0, the latter of which constitute centering fingers for the reiillmember. The shoulder 9 constitutes a seat for the cap washer II which ispreferably of soft compressible material such as rubber which willeffectively seal the space between the lower edge of the cap and theshoulder 9 of the receptacle. A

The upper end of the receptacle is internally threaded as at I2 toreceive the threaded portion I3 of a cap I4. This cap, preferably madefrom the same material as the bottle itself, may be knurled, ribbed orotherwise roughened on its outer surface to provide a hand hold.

The refill member consists of an outer drink ingredient holding shellI5, the open end of which is constricted as at I6 and arranged to beclosed by the insertion therein of the gas cartridge I1. The upper endof the shell at I8 has on its inside the piercing pin I9 which, as seenin Figure 5,

has slots or flutes 20 which permit escape of gas from the gas cartridgeI1 when the end of said cartridge is pierced by the pin. The lower end2I of the cartridge extends slightly beyond the lower end of the shell I5 and rests on the bridge 8 of the support ring 1. The capy I4 at thecenter thereof and on its inner top surface has a compressible Washer orrubber pad 24 which, as well as the top or cap I4, is provided with acentral bore 25 constituting a ventv opening for the release of the topgas pressure when the contents of the rell member have been releasedinto the bottle. Y

It is believed that a full description of the operation is necessary inusing the bottle to prepare a drink and the iirst step is the placing ofthe refill member into the bottle 5 so that it is in the position shownin Figure 1. The cap I4 is then threaded into positions illustrated inFigures 2 and 3 to successively force the shell I5 off the cartridge I'Iand cause the cartridge to be pierced by the pin I9 so that the carbondioxide gas will escape and will force the drink ingredient into theliquid 26 to be prepared. When the cap I4 is threaded down, the washer24 engages the outer surface of the shell I5 with the result that thevent 25 is sealed and continued threading move'- ment of the cap I4forces the shell down to carry out the operation previously described inmaking the drink. The release of thegas will, besides charging theliquid 26, create a to-p pressure, which must be relieved gradually andwithout the conscious effort of the person using the device so that whenthe cap I4 is finallyremoved there will be no boiling over of thecontents of the bottle 5 which would occur if the cap was removedsuddenly. VTo accomplish this, the vent 25 is employed and an initialunthreading movement of the cap will separate the washer 24 and theouter surface of the shell. I5v because the' latter has moved downwardlyand will have no'retr'actile movement thus permitting the gas to escapebefore the lower edge. of the cap I4 leaves the WasherII.V f

In the modified form of the device as shown in Figures 7 to 11inclusive, the receptacle 5 is provided with an annular ledge 30 uponwhich is positioned a bridge 3| constituting a support for the refillunit and also a guide when the same is positioned in the receptacle.This bridge consists of the depending arms 32, the upper ends of Whichare turned over as at 33 to rest on the ledge 30 `while the dependingportions 32 attheir central meeting point are provided with anupstanding cartridge rest 34, Vupon which is supported the cartridge cup2L. which is forcibly fitted over the curved end 2 IB of the gascartridge Y IIA. The lower end of shell ISA is provided with an inwardlyflanged opening, the flange I5c of whichv frictionally holds `the cup2IA therein Vso that the closed end of the vcup is flush with therouter` surface of the cup IBA which holds the liquid to be forced, bythe gas when the latter is released from the cartridge, into the liquidto be prepared. This shell ISA may be provided with a guide ring 35positioned in any suitable manner therein so that the central ring 36thereof holds the cartridge I'IA in upright position so that thepiercing pin I9A in the shell I `5A( will properly pierce the cartridge.f

The cup 2IA also serves as a guide in properly supporting the cartridgewhen it is being pierced. The receptacle 5 in which the liquid 26 to beprepared is held, is closed at its upper end through the medium of a cap36 flanged at its lower end as at 37 to fit over a gasket 38 positionedon a.

ledge 39 at the upper end of the receptacle 5. In order to quicklysecure or remove the cap 36 the same has been provided with headed pins40 at the opposite sides thereof, or at any desired points on theperiphery thereof which are arrang-ed to be engaged by the yoke link 4I,in each instance, which is pivoted as at 42 to the latching hasp arm 43pivoted as at 44, to an extension or ear formed on a plate 45, securedin any suitable manner adjacent the upper end of the receptacle 5.' Thepivot point 44 of the hasp arm 43, being above the pivot point 42 of thelink 4 I, will cause, when the hasp arm is drawn down in the positionindicated in outline in Figure 7, by the arrow, a tightening of the capagainst the gasket 38 and the hasp will act as a latch and will preventaccidental removal or loosening of the cap 36 when once the fasteningdevice has been secured as illustrated. Release of the' cap isaccomplished by raising the arms 43 until the openings 41Ar of arms 4Iwill pass over the heads ofthe pins 40.

The means for releasing the top gas pressure after the formation of thedrink, consists vof a sleeve 46 formed integrally with the cap 36, andin which is threaded as atY 41, a plunger shaft 48, the upper end ofwhich is formed to provide a handle 49 and the plunger shaft itself isprovided with a hollow bore 50 constituting a vent.

The plunger passes through the sleeve 46, and through a packing gland 5Iwhich prevents leakage. The plunger at its lower end and inside the cap36, is provided with a plunger plate SIA, the underside of which iscovered with a compressible seating gasket 52 or rubber pad, Vthe vent5I) passing through the gasket and the plunger plate.

A downward movement of the plunger will bring the gasket into contactwith the outer surface of the shell I5A, to seal the vent 50 andcontinued movement of the plunger will force the shell I5. off the cupv2IA to release the drink ingredient and thereaftery the pin ISA` willpierce the gas cartridge I'IAand the drink will be made. A

reverse threading movement to unscrevm the plunger and raise it, willseparate the gasket and c the shell and uncover the Vent with the resultthat the top gas pressure will be relieved and the cap may be removedwithout danger of the drink being spoiled by the boiling over of thebottle contents. y

It is evident that there has been disclosedal novel container for usewith a refill member which uses a part ofthe member to sealia gaspressure vent and in whicha good'drink can be compoundchanges andmodifications may be made therein without departing from the scope ofthe invention or sacrificing the advantages derivedfrom its use.
